摘要: Since the introduction of the modem apparatus and technology of countercurrent chromatography (CCC), researchers have found numerous applications in the analyses and preparations of natural products. Selection of appropriate solvent systems is a basic and important task for separation in CCC. Recently, we provided an alternative choice of the solvent system by replacing the liquid mobile phase with supercritical-fluid carbon dioxide (SFCO2). In this work, three steroids - progesterone, Delta(4)-androstene-3,17-dione, and (+)-4-cholesten-3-one were separated as test compounds using SFCO2 as the mobile phase and methanol-water (30/70 v/v) solution as the stationary phase.
